There is an installation fee to join the Pine River country club as well as monthly dues the total cost of her seven month membership will be $3200 and after one and a half years $3970 find both the intuition feet and the monthly dues

Answers

Answer:

Monthly charges = $70

Intuition charges = $2710

Step-by-step explanation:

There is intuition fee and per month fee for joining the Pine River country club.

Total cost for 7 months is $3200

Total cost for one and a half years is $3970

one and a half years means 18 months.

To find:

Intuition fee and monthly dues?

Solution:

Let the intuition fee = [tex]i[/tex]

Let the monthly dues = [tex]m[/tex]

Total cost for 7 months can be represented as

[tex]i+7m = 3200[/tex] ..... (1)

Total cost for 18 months can be represented as

[tex]i+18m = 3970 .... (2)[/tex]

Here, we have 2 equations and 2 variables whose values are to be found.

Let us use elimination method to solve the equations.

Subtracting equation (1) from (2):

[tex]11m = 770\\\Rightarrow m = 70[/tex]

Therefore, the monthly dues are $70.

Using equation (1), we can find the value of [tex]i[/tex].

[tex]i + 70\times 7 = 3200\\\Rightarrow i = 3200 - 490\\\Rightarrow i = \$2710[/tex]

Therefore, intuition charges are $2710.

Answer:

BC = [tex] 1.8 [/tex]

Step-by-step explanation:

∆ABC is an equilateral ∆ because all three angles are equal. Therefore, all its sides would be equal also. This means AB = BC = AC

Thus, let's find the value of x.

[tex] \frac{7}{4}x - 1 = \frac{9}{3}x - 3 [/tex]

Collect like terms

[tex] \frac{7}{4}x - \frac{9}{3}x = 1 - 3 [/tex]

[tex] \frac{7x}{4} - 3x = -2 [/tex]

[tex] \frac{7x - 12x}{4} = -2 [/tex]

[tex] \frac{-5x}{4} = -2 [/tex]

Multiply both sides by 4

[tex] \frac{-5x}{4}*4 = -2*4 [/tex]

[tex] -5x = -8 [/tex]

Divide both sides by -5

[tex] x = \frac{8}{5} [/tex]

AB = BC = AC

Therefore,

BC = [tex] \frac{7}{4}x - 1 [/tex]

Plug in the value of x

BC = [tex] \frac{7}{4}*\frac{8}{5} - 1 [/tex]

BC = [tex] \frac{56}{20} - 1 [/tex]

BC = [tex] 2.8 - 1 [/tex]

BC = [tex] 1.8 [/tex]

find the zeros of the function: to the nearest hundredth

Answers

Answer:

The zeros of the function:

[tex]x=5.53 ,[/tex]  [tex]x=3.22[/tex]  

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=2x^2-17.5x+35.6[/tex]

To find zeros, put f(x)=0

[tex]0=2x^2-17.5x+35.6[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]

[tex]0\cdot \:10=2x^2\cdot \:10-17.5x\cdot \:10+35.6\cdot \:10[/tex]

[tex]0=20x^2-175x+356[/tex]

switch sides

[tex]20x^2-175x+356=0[/tex]

subtract 356 from both sides

[tex]20x^2-175x+356-356=0-356[/tex]

[tex]20x^2-175x=-356[/tex]

divide both sides by 20

[tex]\frac{20x^2-175x}{20}=\frac{-356}{20}[/tex]

[tex]x^2-\frac{35x}{4}=-\frac{89}{5}[/tex]

[tex]\mathrm{Add\:}a^2=\left(-\frac{35}{8}\right)^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2-\frac{35x}{4}+\left(-\frac{35}{8}\right)^2=-\frac{89}{5}+\left(-\frac{35}{8}\right)^2[/tex]

applying perfect square

[tex]\left(x-\frac{35}{8}\right)^2=\frac{429}{320}[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solving

[tex]x-\frac{35}{8}=\sqrt{\frac{429}{320}}[/tex]

[tex]x=\frac{\sqrt{2145}}{40}+\frac{35}{8}[/tex]

[tex]x=5.53[/tex]

also solving

[tex]x-\frac{35}{8}=-\sqrt{\frac{429}{320}}[/tex]

[tex]x=-\frac{\sqrt{2145}}{40}+\frac{35}{8}[/tex]

[tex]x=3.22[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]

[tex]x=5.53 ,[/tex]  [tex]x=3.22[/tex]  

Therefore, the zeros of the function:

[tex]x=5.53 ,[/tex]  [tex]x=3.22[/tex]

Given a line with slope of 5 and y-intercept of -1, which of the ordered pairs given below would NOT be on the line?
O (4.18)
(3, 14)
O (0-1)
O (2.9)

Answers

Answer:

(4, 18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

     = 20 - 1

     = 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

      = 15 - 1

      = 14 (Yep, same as option)

3. y = 5(0) - 1

      = 0-1

      = -1 (Yep, same as option)

4. y = 5(2) - 1

      = 10 - 1

      = 9 (Yep, same as option)

The point (4, 18) is not lies on the given line.

First option is correct.

The equation of line in slope intercept form is,

                              [tex]y=mx+c[/tex]

Where m is slope and c is y intercept.

Given that, m = 5 and c = -1

Substitute above values

Equation of line is,

                         [tex]y=5x-1[/tex]

Substitute first option (4, 18) in equation of line.

                     [tex]18=5(4)-1\\\\18=20-1\\\\18=19[/tex], which is invalid equation.

Hence, point (4, 18) is not lies on the given line.

Answer:

The triangles formed are iscocleles triangles making their bases the same angle measures. Additionally, RST anf RGT are congruent since they are each equal to 1/2 of RQTS

We also know that the interior angles of any triangle add up to 180°

Therefore,

m<R + m<T + 126 = 180

m<R + m<T = 54

Since m<R and m<T are equal, R and T must be equal to 27

m<R=27

m<t=27

Therefore,

m<1=27

m<2=27

m<3=27

m<4=27

A biased dice was rolled and the scores recorded in the table below

2. 24
3. 23
4. 10
5. 16
6. 30
A) estimate the probability that on the next roll the score will be 4

Answers

Given:

The table of score and frequency.

To find:

The probability that on the next roll the score will be 4.

Solution:

From the given table it is clear that the score 4 occurs 10 times.

Number of times the dice was rolled = 17 + 24 + 23 + 10 + 16 + 30

                                                             = 120

The probability that on the next roll the score will be 4 is

[tex]\text{Required probability}=\dfrac{\text{Number of times 4 occurs}}{\text{Number of times the dice was rolled}}[/tex]

[tex]\text{Required probability}=\dfrac{10}{120}[/tex]

[tex]\text{Required probability}=\dfrac{1}{12}[/tex]

Therefore, the required probability is [tex]\dfrac{1}{12}[/tex].
